Abstract
Una sonda ultrasónica utilizada en un sistema de telemetría ultrasónica para determinar el volumen del fluido y/o fugas del fluido en un tanque de almacenamiento subterráneo, así como el monitoreo del inventario del fluido, es provista la cual esta caracterizada por: - Reflectores de calibración posicionados en donde cada uno de los paquetes de eco secundario formados por los reflectores de la sonda ultrasónica se encajan dentro del flanco de un paquete de eco primario de otro reflector de calibración o para causar que su paquete de eco secundario sea detectado por el transductor después que el transductor haya detectado un paquete de eco primario asociado con al superficie del fluido. - Cada uno de los reflectores de calibración siendo colocados perpendicular hacia y lateralmente del eje longitudinal del cuerpo de la sonda. - Un miembro amortiguador de onda de sonido ultrasónico colocado firmemente en el cuerpo de la sonda entre el montaje del transductor y el fondo del tanque.An ultrasonic probe used in an ultrasonic telemetry system to determine the fluid volume and / or fluid leaks in an underground storage tank, as well as the fluid inventory monitoring, is provided which is characterized by: - Calibration reflectors positioned where each of the secondary echo packets formed by the reflectors of the ultrasonic probe are embedded within the flank of a primary echo packet from another calibration reflector or to cause its secondary echo packet to be detected by the transducer afterwards the transducer has detected a primary echo packet associated with the fluid surface. - Each of the calibration reflectors being placed perpendicular to and laterally to the longitudinal axis of the probe body. - An ultrasonic sound wave damping member firmly positioned on the probe body between the transducer mount and the tank bottom.
